Necklace



FIG. 1 is a side elevational view of necklace showing my new design;

FIG. 2 is a front elevational view thereof; and,

FIG. 3 is a rear view thereof.

The broken lines shown in the drawings show portions of the necklacewhich form no part of the claimed design.

I claim the ornamental design for a necklace, as shown and described.
